NTP weird dependencies

[deribin]

Hi!

Trying to set up my laptop with small number of packages and found the weird thing. When I'm trying to emerge ntp I got amount of packages to be merged:

Code: Select all

$ emerge -p ntp

These are the packages that I would merge, in order:

Calculating dependencies ...done!

[ebuild  N    ] net-misc/ntp-4.2.0.20050303-r1
[ebuild  N    ] dev-php/php-4.4.0-r4

Can somebody explain me WHY I must install JAVA, APACHE, PHP just to have ntp ??????

PS: building from sources works just fine and solve all my problems, but....

Because ntp depends on swig which depends on php which depends on apache2 and java according to your use flags.

Because ntp depends on swig

Hmmm.... what's it used for by ntp?

[deribin]

Sure I can do:

Code: Select all

env USE="-X -java -perl -php -python" emerge  ntp

But I still wondering why emerging the relatively simple command-line application leads me to emerging so much pakages with "default" flags.

Seems to me that swig is the culprit; use flags like this can sometimes have a "domino effect".
If you dont need the full functionality of ntp you can try openntpd it works nicely, and has far less dependencies.

For me on my machines I have hundreds of clients syncing with each of my servers so I prefer the tools that ntpdc provides.

Another solution would be to set your use flags on a package by package basis using /etc/protage/package.keywords

Sure, I will.
I did it, actually, by using /etc/portage/package.use entry for net-misc/ntp with above flags:

Code: Select all

net-misc/ntp -X -java -perl -php -python

But this "domino effect" looks really strange.
Is it really necessary to use swig here? I just don't see a reason.

PS: It's fair enough for me to use only ntpdate from ntpd package, with help of /etc/init.d/ntp-client script, as I do it on my other computers. Emerging openntpd will not give you this script, that's why I'm playing with ntpd. (yeah, I know, it's stupid. )

net-misc/ntp -X -java -perl -php -python

You're associating the USE flags with the wrong package. The USE flags for the packages would be clear if you run:

Code: Select all

emerge -petv ntp

Stick with ntp, it's excellent.

Portage question, so moved here
